    摘要: Provided is a radio communication base station device capable of acquiring both a multi-user diversity effect and a frequency diversity effect simultaneously in multi-carrier communications. In this devices modulation units (101-1 to 101-n) modulate data to mobile stations (MS#1 to MS#n) individually to create data symbols. A separation unit (102) separates each data symbol inputted, into an Ich (in-phase components) and a Qch (orthogonal components). An Ich arrangement unit (103) and a Qch arrangement unit (104) arrange the Ich and Qch, respectively, in a plurality of sub-carriers constituting an OFDM symbols, and output the same to a synthesization unit (105). This synthesization unit (105) synthesizes the Ich and Qch arranged for each sub-carrier, to create the synthesized symbol.

    摘要: A wireless transmitting apparatus capable of improving the reception error rate of a wireless receiving apparatus. In the inventive apparatus, a channel estimating part (122) acquires a propagation path estimated value. A control part (113) determines whether an estimation precision of the acquired propagation path estimated value is equal to or greater than a predetermined level. A pre-equalization (PE) part applies PE based on the acquired propagation path estimated value to a transport signal if it is determined that the estimation precision is equal to or greater than the predetermined level. Otherwise, the pre-equalization (PE) part avoids the PE application to the transport signal. An RF part (117) transmits the transport signal to which PE has been applied, and transmits the transport signal for which the PE application has been avoided.
